REACH 161 Substances of Very High Concern

On December 17th, 2014, the European Chemical Agency (ECHA) added six new substances to the REACH candidate list of Substances of Very High Concern.

What do PBT and vPvB Mean?

Specifically, PBT stands for Persistent, Bioaccumulative, and Toxic. Next, vPvB stands for very Persistent and very Bioaccumulative. PBT and vPvB substances, such as PFAS, do not easily break down in the environment.

Bioaccumulation occurs when an organism consumes a chemical faster than it eliminates the substance. Thus, the chemical accumulates in the organism’s tissues. When a predator eats the organism, it receives all the collected chemicals in its prey. Therefore, the concentration of bioaccumulative substances exponentially increases up the food chain. This phenomenon is called biomagnification. Furthermore, parents pass down the chemicals to their newborns.

What Are the Criteria for PBT vs. vPvB?

There are criteria that a substance must meet for it to be considered PBT or vPvB by the ECHA.

Firstly, see the difference between a persistent (P) or very persistent (vP) substance in the table below:

Environment

Criteria for Persistent (P)*

Criteria for Very Persistent (vP)*

* Half-life Degradation (in days) higher than…

Secondly, a substance is “bioaccumulative” when its bioconcentration factor in aquatic species is higher than 2000. A substance is “very bioaccumulative” when this factor is higher than 5000.

Finally, the ECHA considers a chemical toxic when it is:

  • Carcinogenic;
  • Mutagenic;
  • Reprotoxic; or
  • Damaging to organs after repeated exposure.

PBTs and vPvBs are harmful to animals, plants, and humans
